'The lubricant hQSe mmay Q cant will 'freely flow through wick 0 tothe parts to be'lubricated. If it is desired to force lubricant under pressure through the wick c to the bearing to belubricated the container a may be filled as already described and after filling the container the lubricant nozzle Z is removed from the nipple i and attached to nipple g. Lubricant under pressure now enters the container a through nippic and, due to the fact that valve hi effectively prevents any escape of oil through nipple 2', a pressure will be built up and lubricant will be forced through passageway 0 under pressure. In this way the lubricant may be forced under high pressure to the bearing to be lubricated to clean and flush,

the latter by a copious flood of fresh oil.

This operation of flushing the bearing also accomplishes a very advantageous result in cleaning the capillary ducts of the wick. After the lubricator has been in use for some time, there is a tendency for the oil to become hardened and, tog-ether with minute foreign particles, to clog the capillary passageways in the wick. Unless this deposit of foreign matter and hardening oil is periodically removed, it will eventually render the wick wholly. incapable of carrying oil to the bearing. I11 the normal use of my improved lubricator the oil will be forced under extremely high pressures through the capillary wick itself and thereby purge the latter of the obstructions in the minute passageways thereof. 7

It will be noted that during the operation of supplying oil under pressure to the lubricator a connection will be made with the valveless nipple 9 so that as soon as this operation is completed the lubricator will immediately be vented to the atmosphere. Thus, even though a small'volumeof air should have been trapped" in the lubricator, this air will not have an opportunityto force the oil through the capillary duct at greater than the desired rate of feed.

In the modification illustrated in Fig. 2 the cover 5 is provided with a nozzle engaging nipple g of the familiar type in which connection is made with the nozzle n of a lubricant gun by direct contact. In the arrangeinent shown in Fig. 2 lubricant is furnished to the container athrough nozzlen and, if desired, lubricant under pressure may be forced through the passageway 0 by building up a pressure in container o through prolonged contact between the nipple g and nozzle 07..

Fig. 3 illustrates a similar arrangement of nipples g and 'i to that shown in Fig. 1 and the lubricating operation will be similar to thatof the device shown in Fig. 1, the material difiierence between the two being that the container on in Fig. 3 is formed in a horizontal manner with the valveless nipple g placed in the uppermost part of the container.

correspondingly, Fig. 4 illustrates a modification ofFig. 2. Y The container (1" is shown as a horizontal container and the nozzle engaging nipple g is situated in the uppermost part of the container. I I I It will be apparent from the foregoing description that a simple and effective wick lubricator has been. provided wherebylubricant may initially be forced to the bearings under-pressure and then lubricant under atmospheric pressure will flow to the bearing to be lubricated due to the capillary attraction of the wick (Z. i

It will further be apparent that an extremely simple arrangement of parts has been provided which does not detract from the efiectiveness of the operation of the device.

WVhile I have illustrated and described a single embodiment of my invention, itwill be readily apparent that many changes and modifications may be made without departing from the spirit of the invention.

WVhat I claim is new and desire to secure by Letters Patent of the United States is:

1. A wick oiler comprising a lubricant container, means on said container for making a quick detachable connection with a source of lubricant under pressure, said means being located adj acent the highestpoint of said container and forming a ductfor free flow in both directions, means for securing said container to a part to be lubricated, said means havin a assa ewa therein a wick in said a p a: y a passageway for conductmg the lubricant sageway, and a valveless air inletand outlet member secured to sald'contamer ad acent the top thereof, said member having nieans,.. for making a quick detachable connection with a lubricant pressuresupply. apparatus. 3. A lubricator comprising acontainer for lubricant, means thereon for making a detachable connection with a source of lubricant. under pressure, said containerhaving anair inlet and outlet passageway communicating with the top thereof, and an oil passageway for conducting oil from the container to a part to be lubricated, means associated with said air passageway for making a detachable connection with a source of lubricant under pressure, and a capillary wick secured in and substantially filling said oil passageway. V

4. A wick oiler comprising a lubricant container, a pair of connectors on said container for making quick detachable connections with a source of lubricant under pressure, one of said connectors being located adjacent the highest point of said container and forming a duct for free flow in both directions and the other of said connectors having a passageway closed by a check valve opening to permit flow into the container and preventing flow therefrom, means for securing said container to a part to be lubricated, said means having a passageway therein forming the only path of communication between said container and a part to be lubricated, and a wick in said passageway for conducting the lubricant from said container to the part to be lubricated by capillary attraction, said wick substantially filling said passageway.

In testimony whereof I aflix my signature.
